Lighting lamp

Abstract

The invention provides a lighting lamp which comprises a base, a rotating device, a heat dissipation barrel, a fixing piece, a rotating barrel, a plurality of LED sub light sources and a plurality of heat dissipation wires. The rotating device comprises a motor and a gear box. The heat dissipation barrel comprises a first heat dissipation layer, a second heat dissipation layer and a third heat dissipation layer which are sequentially stacked. The rotating barrel comprises a light-transmitting layer, an adhesion layer and a projection layer which are sequentially stacked, the side face, away from the adhesion layer, of the light-transmitting layer is fixedly connected with the second end of the fixing piece, and the projection layer is provided with a plurality of projection portions. The two ends of the heat dissipation layers are both arranged on the third heat dissipation layer, and the heat dissipation wires are staggered to form a net-shaped structure. By means of the lighting lamp, heat generated by the LED sub light sources can be rapidly and timely dissipated in the outside air, and the heat dissipation performance is good; besides, the rotating barrel comprises the light-transmitting layer, the adhesion layer and the projection layer which are sequentially stacked, and a good lighting effect and artistic atmosphere can be achieved; the lighting lamp is compact and simple in overall structure and suitable for being applied and popularized on a large scale.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a lighting fixture. Background technique [0002] At present, because LEDs can directly and efficiently convert electrical energy into visible light, and have a service life of tens of thousands of hours to 100,000 hours, and have the advantages of energy saving, LED lamps made of LEDs are characterized by high quality, durability, and energy saving. And other advantages and is used as the most commonly used lighting fixtures. Usually, the basic structure of an LED is a semiconductor P-N junction. When the current flows through the LED element, the temperature of the P-N junction will rise, and the temperature of the P-N junction area is called the junction temperature of the LED. Usually due to The component chips all have a very small size, therefore, the temperature of the LED chip is also called the junction temperature of the LED chip. [0003] It should be pointed out th...
